Abstract
This paper reports on a cooperative research project between the Australian Department of Transport and Regional Services and Transport Canada. This project was a parametric study aimed at better understanding the effects on side impact injury risk of: * Trolley mass * Barrier stiffness * Barrier stiffness distribution * Barrier face height above ground * Crabbed or perpendicular impact * Impact Speed The following observations on injury risk can be made from the tests: * The 2 largest effects for the driver are increasing the height of the barrier face (mainly thoracic) and test speed (all body regions). * Increasing the trolley mass, with a bullet / target mass ratio less than 1, has the effect of increasing only the pubic force. * Doubling the barrier stiffness increases injury risk in only the pelvic area. * The custom high and stiff element (attempting to replicate an SUV) increases both pelvic and abdominal loading.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
